Verified Patient Reviews
All staff very pleasant and positive.
Explained everything and answered all my questions thoroughly to the point that I had no remaining questions at the end of the visit.
I really liked her. She is very thorough and knowledgeable and has a very warm personality. I could ask questions and explained everything. I am switching practices because I really like her as my doctor.
Really took the time to get to know me as an individual. This was my first visit and she made some good recommendations for my health. Looking forward to working with her in the future.
I did not have to wait more than about 5 minutes before they took me back to a room. The nurse took a detailed family health history, including parents, grandparents, siblings, cousins. Dr. Armellini is very personable. Actually seemed to be listening to what I was describing (unlike some doctors I have seen). Discussed other issues that might be causing the symptoms I was having. Office staff was very friendly and efficient as well!
First time visit, very pleased with personal attention. Very easy to talk to. She really listened and asked questions that would assist in the diagnosis. I felt included in the process. She offered detailed feedback that was supported with test results. She seemed to also enjoy helping others become healthier.
Great bedside manner! Spend time with me, even though I was late becuz of traffic :-( Looking forward to working with her to get my T1 Diabetes under control. After feeling defeated for a long time...it was great to feel encouraged and hopeful!
Very thorough, extremely caring, top-notch efficiency. I've already told friends how pleased I am that I have FINALLY found the best Endocrinologist in Virginia! LAL Herndon, VA
Professional, knowledge, efficient, highly recommend
She is very thorough and really takes the time to listen!
I thought the office was efficient and that Dr. Armellini is both personable and knowledgeable. I am very happy that I decided to make Dr. Armellini my endocrinologist.
She's awesome! She takes a very thorough medical history, listens to all concerns, orders tests/follow-up care as necessary, and explains everything carefully.
I just can't say enough about Dr. Armellini. I left in tears of joy. We talked for nearly an hour. She not only asked many questions, but listened to my responses, to my concerns, reviewed my prior labs and records. She's the first doctor that has mentioned things like being gluten free and lab tests other than the standard check of TSH. Thank you Dr. Armellini. I have hope again.
Dr. Armellini and her staff are extremely professional, courteous, thorough, and genuinely cared about my health issues and concerns...best doctor's visit ever!!!!
It was great! She really takes her time with you and makes sure your doing well
Diabetes Stinks. But she's the Best Dr I've seen out of lot of them
Dr. Armellini was patient, thorough, and insightful. I left feeling like I had been heard and was being taken care of appropriately.
This was a great visit. It was my first time to the office, looking for a new endocrinologist, and Dr. Armellini and her staff were great. She spent a long time with me, getting lots of information, asking lots of questions, and outlining a plan of action for me. I was very happy to have found her.
I felt like she was very intelligent, aware of every aspect of the issues why I came to her office. She was organized and thorough and is results oriented.
Dr Armellini is probably one of the best doctors I have ever been to. Her bedside manner is excellent. I was seen at exactly 10:00- my appt time. She was kind, gentle, an excellent listener and I feel like she really knows what she's talking about. i am so thankful that I found her!
She seemed like an expert in her field, plus I appreciated her thorough explanations.
Very nice, caring and thorough. One of the sharpest doctors I have been to. I would highly recommend.
This was my first visit. After mybfollowup visit I will know more.
Could not ask for more! Extremely positive experience.
By far one of the most amazing doctors. I have many insecurities and expectations when it comes to doctors and she has been absolutely perfect. I actually look forward to my next appointment each time one ends.
Excellent, understanding, sensitive and very knowledgeable. Highly recommend her!!
Outstanding! I was very impressed. I had to wait 6 weeks for the first available apt, and I can certainly see why. Dr. Armellini is well worth the wait. She is very caring and intelligent. She has excellent people skills and it's clear that she really knows what she is talking about. I would recommend her to anyone. Her office staff is very caring and efficient too. Thank you for a GREAT experience. I will certainly recommend and return to see her!
Dr. Armellini and her staff is pleasant to deal with. She is very knowledgeable and extremely patient at the same time. I am so glad I found her!
Very understanding, willing to listen, and explains everything very thoroughly. Gave free samples!
Always attentive and thorough
She was very kind and listened to my complaints and discussed my issues. This was my first visit which was positive and look forward to our next appointment.
Spent the time to find out what was going on with me. Very thorough first exam.
We went just based on online reviews. She met our expectations. She is such a professional that she spends at least an hour with the first time patients in trying to understand by going to the detail level of questions, which made us happy. We highly recommend her.
Dr. Denise Armellini was outstanding. She was very informative and the best Endocrinologist I have been to thus far. I would refer other people to her.
Recommended changes to my prescriptions to help my health. I intend to follow through.
Always professional and very personable. I am very confident that she knows her stuff! I trust her a lot.
I heard of Dr. Armellini thorugh a coworker and I'm really glad I did. She is awesome! When I've needed more time and attention, she was a good listener, attentive and reassuring. Her medical advice and management of my condition have been great. At this point, I only have simple follow-up appointments. With other doctors, those have felt impersonal and almost dismissive. That's never been the case with Dr. Armellini. She is extremely good at what she does and has a great bedside manner. Highly recommend!
Dr. Armellini has one of the best bedside manners I've encountered and is very willing to work with the patient to craft an individual care plan. She does not just diagnose and prescribe.
This is the best doctor I have ever been to. And I have been to a lot. She explains everything in detail, and speaks to you like a real person. She takes what you say seriously, and really tries to look at "outside the box" solutions/reasons if necessary. Not only that, but her staff, is kind and organized. Wow. Do not see that often!
She is the best. She takes her time to listen and have a conversation with her patient.. she is very nice and polite as well as very friendly...
I had an unusual request and she did listen to what I told her and also read the writing I gave her. She did answer my questions about hormones as well as she coud.
Dr. Armellini is a wonderful physician. You are greated with a bright smile and a handshake. She "listens" to all of your concerns and addresses them and she also shows concern for her patients. Dr. A., explains everything in detail and will give you a typed copy of what she wants you to do so there are no mistakes in communication. There is nothing I don't like about Dr. Armellini and I HIGHLY recommend her. I drive more than 20 miles to her office so that should tell you something.
She was very thorough and listened to my concerns.
Fabulous doctor who listens to your concerns and addresses each individually. She makes you feel as though you were her only patient. Very happy she is opening her new Fairfax office on October 1.
She is very professional. Easy to talk with and very knowledgably about my medial issues and concerns. I'm pleased!
She was very knowledgeable. I loved my visit.
Very thorough, very easy to talk to. Pleasant and professional. I have already made a referral who booked an appointment.
Very satisfactory. She provided me with a copy of my latest test results, explained her plan for my care in the future.
She is always excellent!
Dr. Armellini is an excellent physician - she's kind, thoughtful, and asks a lot of questions. She is determined to get to the bottom of the issue and will do it in a pleasant and friendly way. She even gave me recommendations for other physicians for other areas I needed to see. I highly recommend her!
Dr. Armellini was very personable, thorough and knowledgeable. She spent a long time listening to my concerns and educating me.
Dr Armellini is incredibly thorough in her history taking and exam. Not only that, she is very kind and easy to talk to. As a patient (and a Registered Nurse), I highly recommend Dr Armellini!!
Great bedside manner, thorough, thoughtful. She did a good job of explaining complex medical terminology without "talking down." Spent a lot of time with me, asked a lot of questions.
Wish I found her 10yrs ago when I first got to be diabetic
The receptionist and doctors all great. Will recommend.
I really good listener and patience.
Dr. Armellini and her staff were exceptional in every way.
She was great, very attentive, and guided me well.
Both Dr Armellini and her staff were fantastic-professional, thorough, knowledgeable, and efficient. I'm really glad to have gotten in as a new patient.
Incredible. What an amazing doctor! Venezuelan doctors are always kind, extremely well prepared and they treat their patients almost like family. That's how they care! And Dr. Armellini is just like that. I couldn't be happier with her and my appointment. I will definitely come back.
Dr. Armellini is great. She is very nice and listens. I wish I could say the same about the location and the staff. After arriving and agreeing to pay $5 for parking in a garage, there were no spots and it took over 20 minutes to park. I was told to arrive 30 minutes before my appointment time to fill out paper work even though I had submitted it via ZocDoc. Then I wasn't seen until 30 minutes AFTER my appointment time. Also, the nurse was not very friendly and didn't seem to listen when she would ask me questions.
personable, kind, efficient. Thorough!
Dr.Armellini is a Class Act! She was very thorough in her examination and keeps you informed with every step. She truly seems to care about your health. She takes her time and talks in detail with you about any concerns. She is truly a jewel and I am very lucky to have found her.
Dr Armellini was very professional and caring. She was knowledgable and took her time going over everything with me. I liked her thoroughness and she had a nice bedside manner too.
Great. I feel lucky to have found her.
Dr. Armellini took the time to collect a thorough medical history, asked lots of questions, and set me up for my next steps. She also went over lab results with me that had been run by another doctor! Very pleasant, thorough, and helpful!
Dr. Armellini's bedside manner alone makes her a keeper. She takes her time, and is careful in diagnosing you and suggesting treatment. This was my first time seen her, she is very thorough. It is a doctor visit; I'm fully satisfied with. I will continue to visit her for my condition.
Dr. Armellini is very thorough, she explained my thyroid condition fully (complete with diagrams!), and has a very warm personality. I would highly recommend her! It should be noted that her office is part of the Virginia Hospital Center complex, so parking in the garage is $4.00.
I absolutely loved my visit with Dr. Armellini. The prior feedback and ratings were ABSOLUTELY on point!!! She is great- very patient- extremely thorough- I never felt rushed (unlike when I visit my primary care Dr.). I wish she was my primary care physician and not a specialist, BUT her depth of knowledge regarding her field makes her very appropriate and fitting right where she is. Loved her....would not see another endo- she even made room to see me during her lunch break because I was late (very) for my appointment and she had a full schedule with no room (Monday off a major holiday). She could have easily said, "reschedule." She didn't and she's great for ALL THE reasons I mentioned- Paul Shelton
She was very thorough, going through medical records with me and explaining herself.
I found her completely uncaring and I was never contacted about any of my results. I was also charged for a missed appointment when I didn't have an appointment scheduled. Additionally you have to pay for parking to see her...completely a waste of my time, money, and resources.
Great physician. Wish the office staff had called me or provided instructions in advance regarding paperwork requirements.
I saw Dr. Armellini this morning for the first time. WOW is the word that comes to mind. I couldn't be happier with our visit. I can't tell you how long it has been since I've actually had a doctor sit down and talk with me. She was patient, professional,thorough and pleasant. We talked about several issues. She not only took the time to talk with me about conditions in her specialty but made a referral for an ENT matter. Thank you! I am looking forward to my follow-up appointment.
Very concerned, thorough and personable. Love her!
this was my first visit. Dr. Armellini was very thorough; she listened and I think she's going to be a good doctor. I am looking forward to folllow up meetings with her
She is very professional, intelligent and was able to explain in our own language (Spanish).
I just transferred my diabetes care to Dr. Armellini, and I am so happy I did! I feel much more confident going forward with my treatment plan. She is a great listener and really makes an appointment a conversation vs. a lecture. Looking forward to meeting with her in the future!
Had initial consultation with Dr. Armellini today and was impressed with her willingness to invest the time explaining the relevant research associated with the various therapies available to me. Her staff was pleasant and efficient - virtually no wait time. I have a follow up with the Dr next month.
Very thorough discussion of my medical history. Provided a detailed explanation of the diagnosis and further testing. Considered symptoms, not just test results in determining diagnosis and treatment.
Dr Armellini was so helpful and knowledgeable. I'm very happy I found her :)
I switched doctors!
Dr. A. was personable, non-judgmental, clear, reasonably concise, and open to discussion. An excellent find.
Outstandingly pleasant and knowledgable Doctor. Willing to listen, and able to educate, the patient.
Dr. Armellini was very thorough and took her time to explain her findings and what will be the next steps. I was extremely happy with her attention, professionalism and calm manner.
Very knowledgeable and helpful, she listens to her patients clinical presentation.
I was very please with dr. Armellini. She was attentive, professional, and spent a lot of time with me to make sure I understood the changes she was making with my medications and why. I'm happy to have found her. Jennifer Kirkpatrick
Dr. Armellini was thorough and kind and explained everything in great detail. She is a wonderful doctor!
Liked her a lot.... A personable type of Doctor. Listen to you, takes her time, and doesn't chastise you. Instead of you need it here's what we are going to do. It's let's work together to fix this thing. Being a Diabetic it is truly hard to be disipline all the time and what need is a Doctor who can be patient and understand that I'm not perfect and will slip from time to time. I believe she is that type of Doctor. Like her!
Most comprehensive exam ever.
Dr. Armellini has outstanding bedside manner. Unlike other Doctor's I have seen, she actually listened to me and is currently running the tests that I should have had done years ago. I would highly recommend to anyone looking for an excellent Endocrinologist.
Excellent, very professional, knowledgeable, explains everything ....great bedside manner. Office staff was also great...will highly recommend!
She seemed very perceptive, a very good listener re my somewhat unconventional presenting issues. Testing/treatment still to happen but I was very impressed by how thorough and intelligent and caring she is.
I have been looking for an endo that will actually listen to what I have to say. I thought Dr. Armellini was most attentive.
Awesome doctor!!! She totally put my mind at ease!
I enjoyed my visits to Dr. Armellini and definitely would recommend her to others. I was hoping that she might be my primary care physician as well, but she is seeing only patients with thyroid issues. She takes her time to explain everything and is very friendly with patients.
she was very helpful and took her time explaining things.
I went to see Dr Armellini about my under active thyroid disorder and a recent questionable PCOS diagnosis from my Gyn. Dr Armellini took the time to explain my lab results, review history and concerns explaining everything and made me feel much better leaving her office with a plan and understanding. She was kind, knowledable and thorough. Highly recommend. The nurse was also very personable and efficent.
I thought Dr Armellini was knowledgeable, kind, patient and thorough.
Excellent .. kind.. patient..would highly recommend.
She seemed very knowledgeable and her bedside manner was excellent. Her questions and examination were very thorough, and she asked for additional tests before making a diagnosis. She inspired great confidence in her abilities and was a pleasure to deal with.
Dr. Armellini was extremely thorough and really took the time to ask me lots of questions and explain things to me. Excellent Doctor!
She was very thorough, kind, and never made me feel that she was rushing me through the appointment.
Just step one but she asked a lot of questions and I hope a positive out come will come down the road here
I really appreciated that she had actually read the medical records that were transferred to her. She knew specifics and asked great questions. She spent a lot of time with me. I'd never had a doctor spend an hour with me before. She was very knowledgeable and said that she'd research what she didn't have answers for. I thought that was very honest.
